Functional asplenia in systemic lupus erythematosus.
A patient with inactive systemic lupus erythematosus was successfully treated for pneumococcal sepsis complicated by disseminated intravascular coagulation, shock, renal failure, and functional asplenia. Functional asplenia was diagnosed from the total absence of uptake of intravenously administered 99mtechnetium-labeled sulfur colloid. Ten similar cases of functional asplenia occurring in patients with systemic lupus erythematosus were noted in a review of the literature. Six of these cases, including the current report, were complicated by pneumococcal (5) or salmonella (1) sepsis. The patient presented here had an excellent antibody response to pneumococcal vaccination. Spleen scan abnormalities fully reversed at 1 year. Although functional asplenia is a rare event in systemic lupus erythematosus, it appears to predispose to severe septic complications.
